SPECIFICATION forming part of Letters Patent No. 368,320, dated August1887- Application filed March 21, 1887. Serial No. 231,753. (No model.)Patented in England May 31, 1884, No. 8,505.

To all whom it may concern:

Be it known that I, THOMAS BOLT, a sub ject of the Queen of GreatBritain, and a resident ofMiddlesborough, in the county of York,England, have invented certain new and useful Improvements in Couplings,(for which I have obtained a patent in Great Britain, No. 8,505, datedMay 31, 1884,) of which the following is a full, clear, and exactspecification thereof.

The object of my invention is to produce an adjustable buffer andcouplings for railroadcars.

Referring to the drawings, Figure I is a plan view of the body of a carembodying my invention. Fig. II is a sectional view of the same.

Fig. Ill is a plan view of a car-body, showing I the ears going around acurve.

A represents the body of the car, B B the wheels, and C C thecrossheads.

D D are the buffer-rods with heads E E. These rods D D slide backwardand forward within the cross pieces 0 c, and are at pointf attached totheendsg g of the elliptical springs G. These springs are hinged fast tothe crossbar e by clamps H.

I I are set-nuts placed on the buffer-rods for the purpose of regulatingthe inward movement of the said rods.

J J are two oscillating bars pivoted to the cross-head O O, and throughthe ends of the bars pass the rods D D.

K K are the couplings. The rods 70 7c of these couplings are pivoted tothe bars J J. The rods It have attached the head at, and the rod It" hasfastened to it the tongue-piece u, with barbed end it within. Thecouplinghead is pivoted or hinged to the jaws L, which are raised byhand or other means and held in position by spring 0. The couplings arearranged on the cars as shown in Fig. I.

By the above arrangement cars are permit ted to go around curves withoutany hinderances from the buffer and ('ouplings,as will 4 be seen in Fig.1H. It will there be observed that the couplings and buffer accommodatethemselves to the movement of the cars.

What I claim is- 1. The adjustable coupling K, constructed as shown, incombination with oscillating bar J and car-body A, substantially as andfor the purpose set forth.

2. In a car-coupling, the combination of coupling K, constructed asshown, and attached to bar J, the buffers E E, with rods 1), havingset-nuts I, and connected to spring G and acting upon the bar J, allarranged substantially for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this9th day of October, 1886.

THOMAS BOLT.
